Luton airport a few years ago. I arrive at security. My bag goes through the scanner. My pass is swiped. All OK.
Security chap: Are you here to work?
Me (smiling): That’s why I’m wearing uniform.
SC: You must answer yes or no.
Me (still smiling): Is this a new procedure?
SC: You must answer yes or no. Are you here to work?
Me (teeth gritted): Yes.
